Can the scaling behavior of electric conductivity be used to probe the self-organizational changes in solution with respect to the ionic liquid structure? The case of [C8MIM][NTf2]

Electrical conductivity of the supercooled ionic liquid [C8MIM][NTf2], determined as a function of temperature and pressure, highlights strong differences in its ionic transport behavior between low and high temperature regions. To date, the crossover effect which is very well known for low molecular van der Waals liquids has been rarely described for classical ionic liquids. This finding highlights that the thermal fluctuations could be dominant mechanisms driving the dramatic slowing down of ion motions near Tg. An alternative way to analyze separately low and high temperature dc-conductivity data using a density scaling approach was then proposed. Based on which a common value of the scaling exponent [gamma] = 2.4 was obtained, indicating that the applied density scaling is insensitive to the crossover effect. By comparing the scaling exponent [gamma] reported herein along with literature data for other ionic liquids, it appears that [gamma] decreases by increasing the alkyl chain length on the 1-alkyl-3-methylimidazolium-based ionic liquids. This observation may be related to changes in the interaction between ions in solution driven by an increase in the van der Waals type interaction by increasing the alkyl chain length on the cation. This effect may be related to changes in the ionic liquid nanostructural organization with the alkyl chain length on the cation as previously reported in the literature based on molecular dynamic simulations. In other words, the calculated scaling exponent [gamma] may be then used as a key parameter to probe the interaction and/or self-organizational changes in solution with respect to the ionic liquid structure.

"Should I prioritize medical problem solving or attentive listening?": the dilemmas and challenges that medical students experience when learning to conduct consultations

Objective: Communication skills can be trained alongside clinical reasoning, history taking or clinical examination skills. This is advocated as a solution to the low transfer of communication skills. Still, students have to integrate the knowledge/skills acquired during different curriculum parts in patient consultations at some point. How do medical students experience these integrated consultations within a simulated environment and in real practice when dealing with responsibility?

Methods: Six focus groups were conducted with (pre-)/clerkship students.

Results: Students were motivated to practice integrated consultations with simulated patients and felt like 'real physicians'. However, their focus on medical problem solving drew attention away from improving their communication skills. Responsibility for real patients triggered students' identity development. This identity formation guided the development of an own consultation style, a process that was hampered by conflicting demands of role models.

Conclusion: Practicing complete consultations results in the dilemma of prioritizing medical problem solving above attention for patient communication. Integrated consultation training advances this dilemma to the pre-clerkship period. During clerkships this dilemma is heightened because real patients trigger empathy and responsibility, which invites students to define their role as doctor.

Practice Implications: When training integrated consultations, educators should pay attention to students' learning priorities and support the development of students' professional identity.

Knowledge dilemmas : the perspective of two Portuguese organisations

A presente investigação pretende examinar se existe uma convergência entre as diferentes percepções dos actores organizacionais, no que respeita à criação e uso/partilha de conhecimento durante o processo de inovação e mudança organizacional. Iremos igualmente tentar compreender se o conhecimento individual – técnico e organizacional – tem impacto na inovação organizacional e no processo de mudança e, consequentemente, no rumo da organização. Iremos conceptualizar o conhecimento individual como conhecimento tácito e assumir que poderá impulsionar a inovação organizacional e, consequentemente, o desenvolvimento da organização. Contudo, iremos assumir que a partilha do conhecimento explícito não poderá ser separada do processo de compreensão, sendo necessário o conhecimento tácito individual para completar a partilha. O conhecimento explícito e o conhecimento tácito serão ambos estudados como dois elementos inseparáveis porque consideramos que o conhecimento explícito necessita de uma compreensão tácita da linguagem que estrutura o conhecimento explícito. Neste contexto, este estudo apresenta as conclusões acerca dos métodos e formas de interacção e partilha de conhecimento entre os actores organizacionais no que toca à inovação organizacional e aos processos de mudança. A informação será recolhida por via de entrevistas e a técnica Group Recall usando a metodologia de investigação-acção. Este estudo contribui, de várias formas, para o desenvolvimento de um quadro teórico e empírico sobre o conhecimento e a partilha de conhecimento tácito em contextos de inovação organizacional e de processos de mudança. Em primeiro lugar, identifica e analisa as diferentes percepções dos actores organizacionais sobre a partilha e o uso do conhecimento individual durante os processos de inovação organizacional. Em segundo lugar, apresenta o impacto do uso do conhecimento individual partilhado e/ou criado durante os projectos de inovação organizacional nos processoe e práticas da organização. Em terceiro lugar, propõe um conjunto de perfis de conhecimento que podem potenciar a criação e partilha de conhecimento entre os actores organizacionais. Em quarto lugar, sugere um modelo facilitador da partilha de conhecimento que pode servir de referência para investigadores e para profissionais das organizações em processos de inovação organizacional e de mudança. Finalmente, este estudo propõe algumas direcções para futuras investigações e sugere algumas questões de estudo que emergiram desta investigação e que poderão ser exploradas.

The effects of chemicals in isopods : a multi-organizational evaluation

The global aim of this thesis was to evaluate and assess the effects of a pesticide (dimethoate) and a metal (nickel), as model chemicals, within different organization levels, starting at the detoxification pathways (enzymatic biomarkers) and energy costs associated (energy content quantification, energy consumption and CEA) along with the physiological alterations at the individual and population level (mortality), leading to a metabolomic analysis (using liquid 1H-NMR) and finally a gene expression analysis (transcriptome and RT-qPCR analysis). To better understand potential variations in response to stressors, abiotic factors were also assessed in terrestrial isopods such as temperature, soil moisture and UV radiation. The evaluation performed using biochemical biomarkers and energy related parameters showed that increases in temperature might negatively affect the organisms by generating oxidative stress. It also showed that this species is acclimated to environments with low soil moisture, and that in high moisture scenarios there was a short gap between the optimal and adverse conditions that led to increased mortality. As for UV-R, doses nowadays present have shown to induce significant negative impact on these organisms. The long-term exposure to dimethoate showed that besides the neurotoxicity resulting from acetylcholinesterase inhibition, this stressor also caused oxidative stress. This effect was observed for both concentrations used (recommended field dose application and a below EC50 value) and that its combination with different temperatures (20ºC and 25ºC) showed different response patterns. It was also observed that dimethoate’s degradation rate in soils was higher in the presence of isopods. In a similar study performed with nickel, oxidative stress was also observed. But, in the case of this stressor exposure, organisms showed a strategy where the energetic costs necessary for detoxification (biomarkers) seemed to be compensated by positive alterations in the energy related parameters. In this work we presented for the first time a metabolomic profile of terrestrial isopods exposed to stressors (dimethoate and niquel), since until the moment only a previous study was performed on a metabolomic evaluation in nonexposed isopods. In the first part of the study we identify 24 new metabolites that had not been described previously. On the second part of the study a metabolomic profile variation of abstract non-exposed organism throughout the exposure was presented and finally the metabolomic profile of organisms exposed to dimethoate and nickel. The exposure to nickel suggested alteration in growth, moult, haemocyanin and glutathione synthesis, energy pathways and in osmoregulation. As for the exposure to dimethoate alterations in osmoregulation, energy pathways, moult and neurotransmission were also suggested. In this work it was also presented the first full body transcriptome of a terrestrial isopod from the species Porcellionides pruinosus, which will complement the scarce information available for this group of organisms. This transcriptome also served as base for a RNA-Seq and a RT-qPCR analysis. The results of the RNA-Seq analysis performed in organisms exposed to nickel showed that this stressor negatively impacted at the genetic and epigenetic levels, in the trafficking, storage and elimination of metals, generates oxidative stress, inducing neurotoxicity and also affecting reproduction. These results were confirmed through RT-qPCR. As for the impact of dimethoate on these organisms it was only accessed through RT-qPCR and showed oxidative stress, an impact in neurotransmission, in epigenetic markers, DNA repair and cell cycle impairment. This study allowed the design of an Adverse Outcome Pathway draft that can be used further on for legislative purposes.

Creativity and problem solving in the development of organizational innovation

This research focuses on creativity and innovation management in organizations. We present a model of intervention that aims at establishing a culture of organizational innovation through the internal development of individual and team creativity focusing on problem solving. The model relies on management’s commitment and in the organization’s talented people (creative leaders and employees) as a result of their ability in defining a better organization. The design follows Min Basadur’s problem solving approach consisting of problem finding, fact finding, problem definition, solution finding and decision implementation. These steps are carried out using specific techniques and procedures that will link creative people and management in order to initiate the process until problems are defined. For each defined problem, project teams will develop possible solutions and implement these decisions. Thus, a system of transformation of the individual and team creativity into organizational innovation can be established.

Dynamics and dilemmas in social psychology: social relations, identities and cognition

This paper aims to provide a systematised overview of the paradigmatic orientations in social psychology in Portugal by identifying the most cited publications. Results show that the eight most cited thematic are: (1) deviance and reactions to deviance, (2) methodology, (3) prejudice and discrimination, (4) gender studies, (5) risk, environment and safety, (6) information processing, social judgment, familiarity and mood, (7) social representations and (8) social justice and belief in a just world. These eight most salient thematics can be sorted into three current paradigmatic orientations in contemporary social psychology: (a) social cognition; (b) the study of collective beliefs, ideologies and social representations; and (c) the study of identity and its impact on intra- and intergroup processes. The paper finishes with a reflection on the future developments of the discipline and the dilemmas that social psychology in Portugal could face.

Social Capital in Inter-Organizational Partnership Research

This chapter focuses on the use of social capital as a construct to examine and explain the formation and operation of inter-organizational partnerships. In particular it shows how social capital contributes to the sustainability of a public sector partnership. In this research context social capital is defined as the networks, trust, norms and values that enable individuals and organizations to achieve mutual goals through collaboration. This definition draws upon the author’s empirical research on partnerships and partnership working in the field of post-compulsory education and her practical experience of establishing, managing and leading international partnerships for teaching and research in teacher education. The emphasis is on the practical application of social capital to qualitative data and on identifying sources of evidence, including research literature from different disciplines in the social sciences to interpret and theorize primary data. The first section of the chapter considers the complexities of defining social capital in the context of rival theoretical and political perspectives and leads to a discussion of the dimensions of social capital that are found in effective and sustained partnerships.

Knowledge creation: revisiting the 'ba' humbug people and 'latent' knowledge in organizational learning

Knowledge management theory has struggled with the concept of `knowledge creation'. Since the seminal article of Nonaka in 1991, an industry has grown up seeking to capture the knowledge in the heads and hearts of individuals so as to leverage them for organizational learning and growth. But the process of Socialization, Externalization, Combination and Internalization (SECI) outlined by Nonaka and his colleagues has essentially dealt with knowledge transfer rather than knowledge creation. This paper attempts to fill the gap in the process - from Nonaka's own addition of the need for "ba" to Snowden's suggestion of that we consider "Cynefin" as a space for knowledge creation. Drawing upon a much older theoretical frame - work the Johari Window developed in group dynamics, this paper suggests an alternative concept - latent knowledge - and introduces a different model for the process of knowledge creation.
